It's an interesting story about the Delf's family move to Lowestoft, but there are some problems with it. William Delf was drowned at 3 o'clock in the morning on the 5th January 1894, whilst engaged as second hand on the trawler "Andrew Marvell" in the North Sea. None of the census returns record that he and his wife Lavinia had any children. On crew records he gives his place of birth as either Beccles or Yarmouth.
